Quantifying nanoparticle size effect on the photoacoustic generation efficiency
Arthur Billon, Sarah Boumati, Lorenzo Mancini +9
Photoacoustic (PA) signal generation in colloidal suspensions of optically absorbing nanoparticles is dominated by the thermal expansion of water for gold nanoparticles, but remain…
Direct observation of the cell-wall remodeling in adhering Staphylococcus aureus 27217: an AFM study supported by SEM and TEM
Rym Boudjemaa, Karine Steenkeste, Alexis Canette +3
We took benefit from Atomic Force Microscopy (AFM) in the force spectroscopy mode to describe the time evolution-over 24h-of the surface nanotopography and mechanical properties of…
Time resolved photoemission spectroscopy of electronic cooling and localization in CHNHPbI crystals
Zhesheng Chen, Min-i Lee, Zailan Zhang +10
We measure the surface of CHNHPbI single crystals by making use of two photon photoemission spectroscopy. Our method monitors the electronic distribution of photoexcite…
Red-emitting fluorescent Organic Light emitting Diodes with low sensitivity to self-quenching
Sebastien Forget, Sebastien Chenais, Denis Tondelier +4
Concentration quenching is a major impediment to efficient organic light-emitting devices. We herein report on Organic Light-Emitting Diodes (OLEDs) based on a fluorescent amorphou…
Pi-stacking functionalization through micelles swelling: Application to the synthesis of single wall carbon nanotube/porphyrin complexes for energy transfer
Cyrielle Roquelet, Jean-Sebastien Lauret, Valerie Alain-Rizzo +8
We report on a new, orginal and efficient method for "pi-stacking" functionalization of single wall carbon nanotubes. This method is applied to the synthesis of a high-yield light-…
Gain measurement and low-threshold laser operation in non-doped thin films made of a small-molecule organic red-emitter
Hadi Rabbani-Haghighi, Sebastien Forget, Sebastien Chenais +3
Stimulated emission in small-molecule organic films at a high dye concentration is generally hindered by fluorescence quenching, especially in the red region of the spectrum. Here…
